Division bar for automobile and method of manufacturing division bar

A method of manufacturing a division bar for an automobile, the division bar provided between a movable door glass and a fixed quarter glass, a first part of the division bar closer to the door glass including an inner-cabin side lip and an outer-cabin side lip, the inner-cabin side lip configured to make elastic contact with an inner-cabin side surface of the door glass, the outer-cabin side lip configured to make elastic contact with an outer-cabin side surface of the door glass, a second part of the division bar closer to the quarter glass including a seal part, the seal part configured to fix a peripheral edge of the quarter glass, the division bar comprising:

• an inner-cabin side member which comprises:
• a receiving part which includes an opening on a part closest to an exterior of the automobile, a plurality of holding lips on an inner side, and a core embedded therein, the core extending in an upper and lower direction of an automobile body, the core being bendable in an inner-cabin and outer-cabin direction;
• the inner-cabin side lip integrally molded with a first part of the receiving part closer to the door glass;
• the seal part integrally molded with a second part of the receiving part closer to the quarter glass;
• and
• an outer-cabin side member which extends in the upper and lower direction of the automobile body, the outer-cabin side member being subjected to bending to have a convex shape toward the exterior of the automobile from an interior in accordance with curvatures of the door glass and the quarter glass, the outer-cabin side member being higher in rigidity than the inner-cabin side member, the outer-cabin side member comprising:
• an anchoring protrusion which extends toward the interior of the automobile;
• the outer-cabin side lip integrally molded with a first part of the outer-cabin side member closer to the door glass;
• and
• a seal lip integrally molded with a second part of the outer-cabin side member closer to the quarter glass;
• the method comprising:
• forming a part of the inner-cabin side member by integrally molding the receiving part, the core, and the inner-cabin side lip by extrusion, then subjecting the part of the inner-cabin side member to bending using bendability of the core to have a convex shape toward the exterior of the automobile from the interior in accordance with the curvatures, arranging the quarter glass as well as the part of the inner-cabin side member on a mold die, and molding the seal part by mold between the receiving part and the quarter glass,
• pulling out the inner-cabin side member from the mold, bringing the outer-cabin side member close to the interior of the automobile to insert the anchoring protrusion of the outer-cabin side member into the receiving part of the inner-cabin side member, and fitting the anchoring protrusion of the outer-cabin side member into the receiving part of the inner-cabin side member, with the outer-cabin side lip making elastic contact with the door glass and with the seal lip making elastic contact with the seal part or the quarter glass.
